Abstract: These two experiments were conducted to examine the characteristics of visual recognition to symmetrical structural Chinese characters by using Naming Tasks. The results indicated that there were significant symmetrical structural effects, the reaction time to symmetrical Chinese characters was significantly shorter than that to nonsymmetrical Chinese characters, There were significant interactions between symmetrical structure and stroke number and character frequency; The symmetrical structural effect only existed in low frequency characters and in more stroke number characters. These showed that the Gestalt radical of symmetrical Chinese characters carried redundant information promoted the processing of recognition of Chinesecharacters. A frequency effect and stroke number effect in recognition of both symmetrical Chinese characters and non-symmetrical Chinese characters were also found in these experiments,

Key words: : visual recognition, Chinese characters, symmetrical structure, character frequency, stroke number
